Where is the equation or expression?
C= 20-0.75x
c= 20-0.75(9)
c= 20-6.75
c= 13.25
Here c is the amount of change and x is the number of books bought.
The customer's change will be $13.25
Answer:
Step-by-step explanation:
slope = y2-y1/x2-x1
Given the coordinates (k,6k) and (3k,10k)
x1 = k
y1 = 6k
x2 = 3k
y2 = 10k
Substitute
slope = 10k-6k/3k-k
slopw = 4k/2k
slope = 4/2
slope = 2
Hence the slope of the line is 2
